Summertime

Similar as to the high school setting and the plot where two boys who grew up together explore romantic feelings and sexual tension towards each other.

Short korean boys love dramas taking place in high school about two guys who have known each other and have been friends since forever navigating and confronting love and feelings as a third person comes to threaten what they have
moments of jealousy and anger
Summertime seems to be alot darker than WYEL, though, and feature more ... kisses etc

-Childhood friends to lovers
-One friend has been CRUSHING for a while
-The parents of both friends were close, but one set of parents passed away so the main characters grow up kinda de facto siblings
-Very lighthearted drama overall, but the romance can get INTENSE sometimes (especially Summertime and the webtoon for Cherry Blossoms)

Similar air of obsession and possessiveness, thanks to a lead character who comes off as dangerously unhinged.

Both are korean boys love dramas produced by OAK Studio with an obsessive and very proactive male lead.
-freaky and sexual content in both
- both are adapted from novels so if you want to dive deeper into the worlds of these characters you can read those

Both are korean boys love dramas produced by Studio OAK with an obsessive, possessive and dominant male lead
Characters longing for somebody with an intense desire and seeking a relationship beyond just "friends" or "cousins"

Childhood friends to lovers, one has an unrequited crush while the other is kind of oblivious, high school romance trope, pining and jealousy ensues, blah blah blah—both are a great watch!

The similarities are that both kind of are seen as adopted brothers but they aren't.
It's just that both families were close and one guy's parents died and then the other family took him in without adoption. The guys grow up together and fall in love with each other. One falls first and keeps that to himself for a while.

The parents don't have an issue with them dating. In Decoding You, it's even a fake marriage in order to deceive someone and ward off bad luck.

*A Shoulder to Cry On* and *Summertime* are somewhat similar as both are **Korean BLs set in a school environment**, focusing on young characters navigating complicated emotions and relationships. Both dramas feature a **school-life setting, youthful romance, friendship, emotional tension, and coming-of-age themes**. The stories also explore characters who initially have a complicated or somewhat distant relationship before gradually developing a deeper emotional connection. Both have a relatively **soft, youthful atmosphere**, while also touching on loneliness, misunderstandings, personal struggles, and the difficulty of expressing feelings. Their romances develop alongside the characters’ personal growth, making the school setting an important part of both stories. However, their specific plots and character dynamics are different.

Both are somewhat similar as both are **K-BLs set in an educational institution**, following young characters as they navigate friendships, emotions, and romance. Both dramas have strong **young-romance vibes**, giving their stories a youthful and relatable feel. They also include moments of **jealousy**, especially as the characters begin developing deeper feelings and become more aware of each other’s relationships and attention. Alongside the emotional tension, both dramas feature a **soft-love** atmosphere, focusing on gentle interactions, growing affection, and the gradual development of romantic feelings. Despite these similarities, their individual storylines and character dynamics remain different.

- Childhood friends to lovers with (more than) a pinch of obsession on one side.
- One lead actively drives away others to stay the second lead's number one
- Height difference
- A good bit of banter between the leads

Forewarning to check tags if you are sensitive to any TWs!
The leads in Secret Lover are (seemingly) a lot more "friendly" (Dohyeon [in Summertime] comes across as a bit more "cold" in nature).
Secret Lover has some fake dating trope moments briefly where as Summertime does not.
